SEMA has issued a press release informing the public that the U.S. Environmental Protection Agency (EPA) is aiming to make it illegal to convert automobiles originally designed for on-road use into racecars, even though such conversions have been done for decades. Under the EPA’s proposed rule, it would also be illegal to sell any performance-related products for those cars. The EPA’s proposal would have a devastating impact on motorsports since many types of racing rely on production vehicles that have been modified for use strictly at the track.
